Ashley Schneider grew up watching her mother, Jill, battle multiple sclerosis with quiet strength. Determined to take action, she founded MS Run the US from her childhood bedroom in Wisconsin, turning her love of running into a mission to raise awareness and funds for those affected by MS.

In 2010, she took it to the next level—running 3,288 miles across America to bring national attention to the cause.

But her journey didn’t end there. She built a nonprofit that now unites runners nationwide to continue the fight.
